Abstract The study aimed to identify the hazard level distribution in the slum areas in Palembang City. The research was a quantitative type with 382 families that live in the slums as the samples. The data were collected using proportional area random sampling and analyzed using the K-means Cluster test through SPSS 23. Spatial analysis through Arcgis was conducted to complete the understanding of the hazard distribution in the slum areas. The results showed that the hazard clusters formed by 64 areas could be categorized into three: low, medium, high. High level of hazards, reaching the one-third portion of the areas, dominated the slums in Palembang City. The cluster with a high hazard level was mostly in the city center, which was geographically located on the riverbanks, causing the areas to be vulnerable to flood, diseases, and crimes. The city center was known to offer high numbers of the job vacancy. People in the slums working in the city center were day laborers.

This study identifies key determinants of Airbnb demand and quantifies their marginal contributions in terms of demand elasticities. A comprehensive cross-sectional data set of all Viennese Airbnb listings that were active between July 2015 and June 2016 is examined. Estimation results, which are obtained by cluster-robust ordinary least squares, show that Airbnb demand in Vienna is price-inelastic. Significant positive drivers include listing size, number of photos, and responsiveness of the host. Significant negative drivers include listing price, distance from the city center, and response time of the host. Implications for the traditional accommodation industry are that, on the one hand, it should better communicate its sought-after advantages (e.g. lower average minimum duration of stay). On the other hand, it should increase its offer of bigger and better equipped hotel rooms since hosting more than two guests at a time is one of the major benefits of Airbnb.

Abstract. One of the consequences of recent glacier recession in the Cordillera Blanca, Peru, is the risk of glacial lake outburst floods (GLOFs) from lakes that have formed at the base of retreating glaciers. GLOFs are often triggered by avalanches falling into glacial lakes, initiating a chain of processes that may culminate in significant inundation and destruction downstream. This paper presents simulations of all of the processes involved in a potential GLOF originating from Lake Palcacocha, the source of a previously catastrophic GLOF on 13 December 1941, killing about 1800 people in the city of Huaraz, Peru. The chain of processes simulated here includes (1) avalanches above the lake; (2) lake dynamics resulting from the avalanche impact, including wave generation, propagation, and run-up across lakes; (3) terminal moraine overtopping and dynamic moraine erosion simulations to determine the possibility of breaching; (4) flood propagation along downstream valleys; and (5) inundation of populated areas. The results of each process feed into simulations of subsequent processes in the chain, finally resulting in estimates of inundation in the city of Huaraz. The results of the inundation simulations were converted into flood intensity and preliminary hazard maps (based on an intensity-likelihood matrix) that may be useful for city planning and regulation. Three avalanche events with volumes ranging from 0.5 to 3  ×  106 m3 were simulated, and two scenarios of 15 and 30 m lake lowering were simulated to assess the potential of mitigating the hazard level in Huaraz. For all three avalanche events, three-dimensional hydrodynamic models show large waves generated in the lake from the impact resulting in overtopping of the damming moraine. Despite very high discharge rates (up to 63.4  ×  103 m3 s−1), the erosion from the overtopping wave did not result in failure of the damming moraine when simulated with a hydro-morphodynamic model using excessively conservative soil characteristics that provide very little erosion resistance. With the current lake level, all three avalanche events result in inundation in Huaraz due to wave overtopping, and the resulting preliminary hazard map shows a total affected area of 2.01 km2, most of which is in the high hazard category. Lowering the lake has the potential to reduce the affected area by up to 35 %, resulting in a smaller portion of the inundated area in the high hazard category.

Since the year 1998 up to the mid of 2005, in the district ofBanjarsari, there happened an increasing amount of slum areas which might endanger the environmental balance. This research aims at (1) identifying the shift of distribution pattern from the settlement diffusion in the district of Banjarsari Surakarta in the year 2001-2005. (2) Identifying the alteration form of the unoccupied land into slum areas in the district of Banjarsari Surakarta. (3) Identifying the characteristics of slum area dwellers in the district of Banjarsari Surakarta. This research uses the survey method, secondary data analysis and map analysis. The data ar alysis used is tlie closest neighbor analysis, table of frequency, crossed tables and descrip ave analysis. The result shows that (1) the distribution pattern of the slum areas appeared in the district ofBanjarsari in the year 2001 is the random distribution pattern while the one in 2005 is the dissemination pattern. Such pattern indicates the grc wing amount and interraction with the means of transportation and economic condition in those slum areas. (3) The lands which are altered into slum areas in the district of Banjarsari during 2001-2005 take place in the unoccupied areas owned by the state.(3) The distribution of age among the slum area inhabitants is around 41-61 years of age (49%) while tb biggest amount is the new arrivals (57%). The region of Sub province Sragen has the bigges percentage in the distribution of the city inhabitants origin in the district of Banjarsari. Regionally, the inhabitants who come from the hinterland of Surakarta or ex Surakarta residency took the amount lof 73.68%. The highest percentage of educational level of the slum area inhabitants in the district of Banjarsari is the uneducated residents or those from low education level (55%). Most of the respondents occupations of the slum area dwellers in Banjarsari are in the informal sectors (82%) The number of family member in the district of Banjarsari is around l-

ABSTRACTCities are spatial plans on the surface (land) with administrative boundaries that have been determined where there is concentration of the population in it along with various economic, social and political activities. The city is a residential spatial structure with a large number of people on limited urban land, which is generally non-agrarian. The development of the city does not always have a positive impact, but it has a negative impact including the emergence of slum areas around the city center. Around the city center there are various centers of activity including tourism, health, education and trade as well as services in the city, provincial and national levels. The five activities are developing quite rapidly which has resulted in the development of residential areas around the city center and the poor development of slums in these locationsThe purpose of this study is to analyze the factors that influence the development of slums. The research location is in the city of Bukittinggi, West Sumatra Province. This study uses primary data by distributing questionnaires to households throughout the City of Bukittinggi. The analysis used is logistic regression analysis. The results showed the factors that influence the development of slums including the Quality of Dwelling, Building Density, Education and Road Accessibility. These influencing factors can be used as a reference for alleviating slums in Bukittinggi City.Keywords: cities, households, slum areas. ABSTRAKKota merupakan suatu tempat pemusatan berbagai kegiatan manusia baik dari kegiatan sosial, kegiatan ekonomi, maupun kegiatan politik dimana berkonsentrasi pada satu tata ruang di atas permuakaan (darat) yang memiliki batas-batas wilayah administrasi yang sudah ditetapkan. Kota merupakan suatu tata ruang permukiman berpenduduk dengan jumlah yang banyak di atas lahan perkotaan yang terbatas, yang pada umumnya bersifat non agraris. Perkembangan kota tidak selalu menimbulkan dampak positif, namun memiliki dampak negatif diantaranya munculnya kawasan permukiman kumuh di sekitar pusat kota. Di sekitar pusat kota memiliki berbagai pusat  kegiatan diantaranya pariwisata, kesehatan, pendidikan dan perdagangan serta jasa baik di lingkup kota, provinsi maupun nasional. Kelima kegiatan tersebut berkembang dengan cukup pesat yang mengakibatkan berkembang kawasan permukiman di sekitar pusat kota dan buruknya berkembang permukiman kumuh di lokasi tersebut. Tujuan dari penelitian ini adalah untuk menganalisis faktor-faktor yang mempengaruhi perkembangan permukiman kumuh. Lokasi penelitian berada di Kota Bukittinggi Provinsi Sumatera Barat. Penelitian ini menggunakan data primer dengan menyebarkan kuesioner ke rumah tangga se-Kota Bukittinggi. Analisis yang digunakan adalah analisis regresi logistik.

Monitoring of the rivers state and the environment of roads in the city center is often still inadequate. For example, garbage is often found in the river, while on the roads, there is still not yet a sound security system. Kauman RT 03 RW III Klojen Malang is one of the densely populated regions and is located in the center (point of zero) of Malang city at the time ago still does not have a security system or security guard and there is a river flow which is often found garbage piling up and often causes flooding when it rains heavy. Based on field conditions in Kauman and meetings with residents represented by several RT heads in RW 03 Kauman, Klojen Malang requires the use of a smart environment and CCTV technology integration. Therefore the result of dedication to society to apply CCTV's technology, so it has been used at Kauman for environmental and security monitoring. Considering the high level of the busyness of the urban at Kauman, with providing it, they can be monitoring the environment by automatically systems continuously 24 hours every day. Therefore, the system has been being able to facilitate and help people to monitor the environment and river flow to be more effective, efficient, and modern. ABSTRAKMonitoring keadaan sungai dan lingkungan ruas jalan pada masyarakat tengah kota seringkali masih belum memadai. Di aliran sungai misalnya, masih sering dijumpai sampah yang menumpuk, sedangkan di ruas jalan masih belum dijumpai sistem keamanan yang baik. Kampung Kauman RT 03 RW III kecamatan Klojen Kota Malang merupakan salah satu kampung yang padat penduduk dan berada di pusat (titik nol) kota saat ini belum memiliki sistem keamanan ataupun satpam dan terdapat aliran sungai yang seringkali dijumpai sampah menumpuk bahkan sering menyebabkan banjir bila hujan deras. Berdasarkan kondisi lapangan di kampung Kauman dan pertemuan dengan warga yang diwakili oleh beberapa ketua RT di wilayah RW 03 Kauman yang membutuhkan pemanfaatkan integrasi teknologi smart environment dan teknologi CCTV. Hasil kegiatan pengabdian masyarakat telah dapat secara optimal dimanfaatkan untuk memenuhi kebutuhan pengawasan ataupun monitoring lingkungan tersebut. Mengingat tingkat kesibukan masyarakat perkotaan yang tinggi, dengan adanya sistem monitoring mereka dapat mengambil manfaat besar dengan dikembangkannya sistem pengawasan aliran sungai dan lingkungan yang bisa bekerja secara otomatis dan kontinyu selama 24 jam. Sistem yang dibuat telah mampu memudahkan sekaligus membantu masyarakat untuk monitoring lingkungan dan aliran sungai secara lebih efektif, efisien, dan modern.

Abstract- Restaurants and cafes as the recreation, relaxation and entertainment facilities forms have grown continuously with its endless innovation. This aspect of continuous growth is to respond to consumptive society's demand as the result of the continuous development of the modern era. This globalization era leads society to know the information and communication technology that affects their social life. Lifestyle and become an individual's identity and has been considered as the key to their social life through social media. Thus the architecture in the culinary world can be post it up in their social media. The innovation found in Atmosphere Resort Café is the ambiance of a resort in this city that is located in the city center area of Bandung city, Lengkong Besar Street. This area is the area of trading and housing, and is the one way to play street at the area. Atmosphere Resort Café wishes to present a different ambience at this city center through the concept of a resort café, also to be different from other cafés. To be located in the city center is a challenge to be able to present the resort ambience which is commonly found in suburban areas, away from the city center itself. Thus, how can a sense of place with the resort be presented at Bandung city center to be an oasis is an interesting topic to be discussed. Atmosphere Resort Cafe has a characteristic sense of place, and its impact to the guests and users. The method used is a qualitative approach by explaining its regional context and resort characteristics, and to explain the sense of place components that are setting in physical systems and users to understand the psychological reaction. The setting in its physical system includes identity and physical elements, while the user includes the quality they feel toward the setting. The datas are obtained through field observation, literature studies, interviews, questionnaires as responders, and documentation. It is concluded that the resort characteristic in this city center has a strong landscape of architecture as one of the main elements in the Atmosphere Resort Café. Besides that, the existing massing and space, strengthened the reflection of nature, has created a stronger characteristic and the city center resort, full of hustle and bustle, is a shut down through the created control of space. The settings also passed in stimulating user awareness and perception. Users feel relax and happy when they are in At the atmosphere Resort Café with its ambience. Accordingly Atmosphere Resort Café has these places as a resort, a café that strengthens its identity in Bandung city center. Key Words: Sense of place, resort, oasis, Bandung city center

In order to achieve the objectives of Smart Cities, public administrations need to take measures to regulate mobility, which undoubtedly requires a high level of information and sensorization. Until the implementation of the connected vehicle takes place, it is still necessary to install sensors to obtain information about mobility. Bluetooth sensors are becoming a useful tool due to the low cost of equipment and installation. The use of Bluetooth sensors in cities, with short distances between sensors, makes it necessary to propose new classification algorithms that allow the trips of pedestrians and vehicles to be differentiated. This article presents the study carried out in the city of Valencia to determine the use of motor vehicles in the historic center and propose a new classification algorithm to distinguish between an onboard Bluetooth device and the same device carried by a pedestrian when it is not possible to use the travel time for the classification due to the short distance between sensors. This causes very similar or even indistinguishable travel times for vehicles and for pedestrians. We also propose an algorithm that allows vehicles to be classified according to what type of trip is made always through the historical center of Valencia, whether it is to make a shorter itinerary through the city or to access the center for any type of business. This algorithm would enable the Origin-Destination matrix of an urban network with short distances between sensors if they are available in all entries and exits. Likewise, the results obtained have allowed to positively evaluate the algorithm defined to distinguish between trips made by a pedestrian or a vehicle in a city, using the MAC address of their mobile devices with very short distances among sensors. The results of this study show that it is possible to use Bluetooth technology, with low cost installations, to evaluate the use of the city by motor vehicles.

In the most liquid environments that characterize nightlife and parties, we generally live in a slower and more marked time: on the one hand, by relevant, varied and often intense sensitive experiences; and, on the other hand, for expectations of more freedom and social interaction between the actors. This article sought to problematize the direct and indirect repercussions - not only socioeconomic, but especially in the imagination of the city - of the nightly cultural experiences that take place at the festive events held at Beco das Artes (in the city center of Rio de Janeiro), which it presents itself as an open territory for serendipities, capable of mobilizing an expressive segment of actors who gravitate towards a musical production associated with the local alternative scene (and who, in general, participate in the current street culture in Rio). In view of the objectives outlined, our investigation is not only based on the theoretical-methodological procedures of the Sociology of Senses (and of the Imaginary) founded by Georg Simmel, but also employs cartographic methodological strategies (in the process of carrying out fieldwork and monitoring the dynamics aggregation of actors in the territories) inspired by the Actor-Network Theory, noted in Bruno Latour's seminal work.

Abstract: Uric acid is an end product of purine metabolism in humans. Serum uric acid levels increased significantly to those who are obese. In people who have a form of body fat tend to be more easily and have a high risk of gout due to decomposition of food with high level of purine and fats that mixed in blood is difficult to excreted through urine, resulting in the accumulation and clogging fats in the blood. This study aims to describe uric acid in obese adolescents. This research is a descriptive cross sectional approach. The sampling technique used is the technique of random sampling. Samples were taken from the high school students in the city of Bitung that obesity is determined by measuring waist circumference. Then students who are willing to be sampled were asked to sign an informed consent and fasting of at least 10-12 hours, then take the blood for examination of blood uric acid levels. The prevalence of adolescents obesity that have uric acid increased in Bitung is 56%. In research conducted on 50 students of obesity, found 28 (56%) of people have increased uric acid, which consists of 8 (16%) persons of male students and 20 (40%) persons of female students.Keyword : uric acid, obecityAbstrak: Asam urat merupakan produk akhir metabolisme purin pada manusia. Kadar asam urat serum meningkat secara signifikan terhadap mereka yang mengalami obesitas. Pada orang yang memiliki bentuk tubuh gemuk cenderung lebih mudah dan memiliki resiko tinggi terkena penyakit asam urat karena proses penguraian makanan purin yang bercampur lemak dalam darah sulit dikeluarkan melalui urine, sehingga terjadi penumpukan dan penyumbatan lemak dalam darah. Penelitian ini bertujuan untuk mengetahui gambaran asam urat pada remaja obesitas. Penelitian ini berupa cross sectional dengan pendekatan deskriptif. Teknik pengambilan sampel yang digunakan adalah dengan teknik random sampling. Sampel penelitian diambil dari siswa-siswi SMA dikota Bitung yang obesitas yang ditentukan dengan mengukur lingkar pinggang. Kemudian siswa yang bersedia dijadikan sampel diminta untuk menandatangani informed consent dan melakukan puasa minimal 10-12 jam, kemudian diambil darah untuk dilakukan pemeriksaan kadar asam urat dalam darah. Prevalensi remaja obesitas yang mengalami peningkatan asam urat di Kota Bitung adalah 56%. Dalam penelitian yang dilakukan pada 50 siswa obesitas, didapatkan 28 (56%) orang mengalami peningkatan asam urat, yang terdiri dari 8 (16%) siswa laki-laki dan 20 (40%) siswa perempuan.Kata kunci : asam urat, obesitas
